From ebcfd86a2ee6c08419b951d8176febaf683e9726 Mon Sep 17 00:00:00 2001 From: "Frank Ch. Eigler" Date: Sun, 5 Apr 1998 16:40:03 +0000 Subject: [PATCH] * R5900 COP2 function nearly complete. PKE sim now aware of new GPUIF masking facility for PATH3 transfers. [ChangeLog.sky] Sun Apr 5 12:11:45 1998 Frank Ch. Eigler * sky-libvpe.c (exec-inst): Added "M" bit detection for upper instruction. * sky-pke.c (pke_check_stall): Added more assertions. (pke_code_mskpath3): Use new GPUIF M3P control register. * sky-pke.h (VU[01]_CIA): New macros that give VU CIA pseudo-register addresses. * sky-vu.h (vu_device, VectorUnitState): Merged structs. (VectorUnitState.mflag): New field. (VU_REG_{CMSAR0,CMSAR1,FBRST}) Added missing control registers. * sky-vu.c (vu0_busy): New function. (vu0_q_busy): New function. (vu0_macro_issue): New function. (vu0_micro_interlock_released): New function. (vu0_busy_in_{micro,macro}_mode): Deleted stubs. (vu0_macro_hazard_check): Deleted stubs. (vu_attach): Adapted code to merged device & state struct. (read_vu_special_reg): Compute VBS0/VBS1 bits in STAT register. [ChangeLog] start-sanitize-sky Sun Apr 5 12:05:44 1998 Frank Ch. Eigler * interp.c (*): Adapt code to merged VU device & state structs. (decode_coproc): Execute COP2 each macroinstruction without pipelining, by stepping VU to completion state. Adapted to read_vu_*_reg style of register access. * mips.igen ([SL]QC2): Removed these COP2 instructions. * r5900.igen ([SL]QC2): Transplanted these COP2 instructions here. * sim-main.h (cop_[ls]q): Enclosed in TARGET_SKY guards. end-sanitize-sky --- sim/mips/ChangeLog | 16 + sim/mips/interp.c | 214 +++++---- sim/mips/mips.igen | 1056 +++++++++---------------------------------- sim/mips/sim-main.h | 8 +- sim/mips/sky-pke.c | 9 +- sim/mips/sky-pke.h | 3 + 6 files changed, 371 insertions(+), 935 deletions(-) diff --git a/sim/mips/ChangeLog b/sim/mips/ChangeLog index f820155f24..1804d5c752 100644 --- a/sim/mips/ChangeLog +++ b/sim/mips/ChangeLog @@ -1,3 +1,19 @@ +start-sanitize-sky +Sun Apr 5 12:05:44 1998 Frank Ch.
